EMRO-150 Odor Eliminator is not a mask, cover up, or perfume—it’s formulated to attack and destroy the source of the odor. It contains a patent pending odor modification agent formulated to work almost instantly with odors that contain nitrogen or sulfur. EMRO-150 works through co-valent bonding, meaning that the deodorizer and odor source share elections at the molecular level. In addition, it also acts as a mild oxidizer and continues to remove the odor as it dries. Not intended to replace all other types of deodorizers, EMRO-150 is designed to work well as a first response to most odors.
